Taxonomic Approach

The taxonomic position of a marine actinomycete, strain SJS0289/JS1T, was determined using a polyphasic taxonomic approach. The organism, which had phenotypic properties consistent with its classification in the genus Williamsia, formed a distinct clade in the 16S rRNA gene tree together with the type strain of Williamsia muralis, but was readily distinguished from this species using DNA–DNA relatedness and phenotypic data. The genotypic and phenotypic data show that the organism merits recognition as a new species of Williamsia. The name proposed for the new species is Williamsia maris; the type strain is SJS0289/JS1T (=DSM 44693T=JCM 12070T=KCTC 9945T=NCIMB 13945T).

The taxonomic position of an actinomycete, strain IMMIB L-889T, isolated from the sputum of a 64-year-old man, was determined using a polyphasic taxonomic approach. The strain had chemical and morphological properties that were consistent with its classification in the genus Actinomadura. It formed a distinct phyletic line in the 16S rRNA gene tree of Actinomadura and was most closely related to the type strain of Actinomadura hallensis (98.4 % sequence similarity), but could be readily distinguished from the latter species using DNA–DNA relatedness and phenotypic data. The combined genotypic and phenotypic data indicate that strain IMMIB L-889T represents a novel species of the genus Actinomadura, for which the name Actinomadura sputi sp. nov. is proposed. The type strain is IMMIB L-889T (=DSM 45233T=CCUG 56587T).

Taxonomic Approach

The taxonomic status of an actinobacterial strain isolated from Mariana Trench sediment was determined using a polyphasic taxonomic approach. The strain, isolate MT1.1T, formed a distinct clade in the Micrococcineae 16S rRNA gene tree together with Dermacoccus nishinomiyaensis DSM 20448T. The organism had chemical and phenotypic properties consistent with its classification in the genus Dermacoccus and could be distinguished from D. nishinomiyaensis DSM 20448T using DNA–DNA relatedness and phenotypic data. The G+C content of the DNA of isolate MT1.1T was 65.2 mol%. It is evident that the organism merits recognition as a novel species in the genus Dermacoccus. The name proposed for this taxon is Dermacoccus abyssi sp. nov.; the type strain is MT1.1T (=DSM 17573T=NCIMB 14084T). The organism grows well at 40 MPa and hence is piezotolerant.

Gene Similarity

The taxonomic relationships of two actinomycetes provisionally assigned to the genus Rhodococcus were determined using a polyphasic taxonomic approach. The generic assignment was confirmed by 16S rRNA gene similarity data, as the organisms, strains MTCC 1534 and W 4937T, were shown to belong to the Rhodococcus rhodochrous subclade. These organisms had phenotypic properties typical of rhodococci; they were aerobic, Gram-positive, weakly acid-fast actinomycetes that showed an elementary branching-rod–coccus growth cycle and contained meso-diaminopimelic acid, arabinose and galactose in whole-organism hydrolysates, N-glycolated muramic acid residues, dehydrogenated menaquinones with eight isoprene units as the predominant isoprenologue and mycolic acids that co-migrated with those extracted from the type strain of R. rhodochrous. The strains had identical phenotypic profiles and belong to the same genomic species, albeit one distinguished from Rhodococcus pyridinivorans, with which they formed a distinct phyletic line. They were also distinguished from representatives of all of the species classified in the R. rhodochrous 16S rRNA gene tree using a set of phenotypic features. The genotypic and phenotypic data show that the strains merit recognition as a novel species of Rhodococcus. The name proposed is Rhodococcus gordoniae sp. nov., with the type strain W 4937T (=DSM 44689T=NCTC 13296T).

Phyletic Line

The taxonomic position of a Streptomyces strain isolated from an extreme hyper-arid soil sample collected from the Atacama Desert was determined using a polyphasic approach. The strain, isolate C60T, had chemical and morphological features typical of members of the genus Streptomyces and formed a distinct phyletic line in the Streptomyces 16S rRNA gene tree, together with the type strain of Streptomyces radiopugnans . The two strains were distinguished readily using a combination of phenotypic properties and by a DNA–DNA relatedness value of 23.17 (±0.95) %. On the basis of these genotypic and phenotypic data, it is proposed that isolate C60T ( = CGMCC 4.7018T = KACC 15492T) be classified in the genus Streptomyces as Streptomyces atacamensis sp. nov.

Type Strains

The taxonomic positions of two actinobacterial strains isolated from Mariana Trench sediment were established using a combination of genotypic and phenotypic data. The strains, isolates MT2.1T and MT2.2T, formed a distinct phyletic line in the Micrococcineae 16S rRNA gene tree together with Dermacoccus abyssi NCIMB 14084T. The isolates had chemical and phenotypic properties typical of members of the genus Dermacoccus and could be distinguished sharply from one another and from the type strains of Dermacoccus abyssi and Dermacoccus nishinomiyaensis using DNA–DNA relatedness data. A range of phenotypic properties served to distinguish the two novel strains from one another and from the type strains of established Dermacoccus species. The G+C contents of the DNAs of strains MT2.1T and MT2.2T were 66.8 and 69.1 mol%, respectively. It is evident that the two isolates merit recognition as novel species within the genus Dermacoccus. The names proposed for these taxa are Dermacoccus barathri sp. nov. (type strain MT2.1T=DSM 17574T=NCIMB 14081T) and Dermacoccus profundi sp. nov. (type strain MT2.2T=DSM 17575T=NCIMB 14084T).

Phenotypic Data

A polyphasic study was undertaken to determine the taxonomic status of six strains received as Streptomyces hygroscopicus. The strains had chemotaxonomic and morphological properties typical of members of the genus Streptomyces and formed distinct phyletic lines in the Streptomyces 16S rRNA gene tree. These strains were distinguished from one another and from phylogenetically close neighbours using a combination of phenotypic properties. The combined genotypic and phenotypic data showed that all six strains form distinct centres of taxonomic variation within the genus Streptomyces. The following novel species are proposed to accommodate the strains: Streptomyces aldersoniae sp. nov. (type strain DSM 41909T =NRRL 18513T), Streptomyces angustmyceticus sp. nov., comb. nov. (type strain DSM 41683T=NRRL B-2347T), Streptomyces ascomycinicus sp. nov. (type strain DSM 40822T =NBRC 13981T), Streptomyces decoyicus sp. nov., comb. nov. (type strain DSM 41427T =NRRL 2666T), Streptomyces milbemycinicus sp. nov. (type strain DSM 41911T =NRRL 5739T) and Streptomyces wellingtoniae sp. nov. (type strain DSM 40632T =NRRL B-1503T).

A New Species

In the course of a polyphasic study it was observed that ‘Dactylosporangium variesporum’ NRRL B-16296 is misclassified in the genus Dactylosporangium as it exhibits properties consistent with its assignment to the genus Saccharothrix. Phylogenetic analyses based on 16S rRNA gene sequences show that the strain falls within the evolutionary radiation of the genus Saccharothrix, a result which is supported by corresponding chemotaxonomic and morphological markers. The strain is phylogenetically most closely, albeit loosely, related to Saccharothrix espanaensis, but can be readily distinguished from this and other species of the genus Saccharothrix with validly described names by using a range of phenotypic properties. The combined genotypic and phenotypic data demonstrate conclusively that this strain should be classified as a new species in the genus Saccharothrix for which the name Saccharothrix variisporea sp. nov. is proposed. The type strain is NRRL B-16296T (=ATCC 31203T =DSM 43911T =JCM 3273T =NBRC 14104T).

Strain SB026T was isolated from Brazilian rainforest soil and its taxonomic position established using data from a polyphasic study. The organism showed a combination of chemotaxonomic and morphological features consistent with its classification in the genus Amycolatopsis and formed a branch in the Amycolatopsis 16S rRNA gene tree together with Amycolatopsis bullii NRRL B-24847T, Amycolatopsis plumensis NRRL B-24324T, Amycolatopsis tolypomycina DSM 44544T and Amycolatopsis vancoresmycina NRRL B-24208T. It was related most closely to A. bullii NRRL B-24847T (99.0 % 16S rRNA gene sequence similarity), but was distinguished from this strain by a low level of DNA–DNA relatedness (~46 %) and discriminatory phenotypic properties. Based on the combined genotypic and phenotypic data, it is proposed that the isolate should be classified in the genus Amycolatopsis as representing a novel species, Amycolatopsis rhabdoformis sp. nov. The type strain is SB026T ( = CBMAI 1694T = CMAA 1285T = NCIMB 14900T).

A soil actinomycete, strain 80-133T, with the non-validly published name ‘Microstreptospora cinerea’, was the subject of a polyphasic study designed to clarify its taxonomic status. Comparative 16S rRNA gene sequence studies indicated that the organism belonged to the genus Streptomyces, a result in line with previous chemotaxonomic and morphological data. The strain belonged to the Streptomyces griseus clade, but could be distinguished from representatives of species assigned to this taxon by using DNA–DNA relatedness and phenotypic data. In light of these findings, it is proposed that the organism should be recognized as a novel species of the genus Streptomyces. The name proposed for this taxon is Streptomyces yanii sp. nov., with isolate 80-133T (=AS 4.1146T=JCM 3331T) as the type strain. It was also shown that representative strains of Streptomyces argenteolus, Streptomyces caviscabies, S. griseus and Streptomyces setonii belong to the same genomic species and have key phenotypic properties in common. It is proposed that S. caviscabies and S. setonii should be considered as later heterotypic synonyms of S. griseus and that S. argenteolus AS 4.1693T should also be assigned to this taxon.

The taxonomic positions of two thermophilic actinomycetes isolated from an arid Australian soil sample were established based on an investigation using a polyphasic taxonomic approach. The organisms had chemical and morphological properties typical of members of the genus Amycolatopsis and formed distinct phyletic lines in the Amycolatopsis methanolica 16S rRNA subclade. The two organisms were distinguished from one another and from the type strains of related species of the genus Amycolatopsis using a range of phenotypic properties. Based on the combined genotypic and phenotypic data, it is proposed that the two isolates be classified in the genus Amycolatopsis as Amycolatopsis thermophila sp. nov. (type strain GY088T = NCIMB 14699T = NRRL B-24836T) and Amycolatopsis viridis sp. nov. (type strain GY115T = NCIMB 14700T = NRRL B-24837T).
